GitHub Action workflow is not YAML!

Why aren’t GitHub Action workflows written in YAML? They are YAML-like but don’t, for example, support anchors. As a short term could the developers support this?

  • Workflow is written using YAML comlpete with anchors etc
  • YAML is read and then written out as expanded “GitHub Actions YAML”
  • From here, the existing GitHub Actions processing should be able to handle the intermediate file.
